On April 28, 2018, PDTU-800 SF6 frequency conversion series resonant device independently researched and developed by Shandong Taikai Instrument Transformer Co., Ltd, successfully completed all the test items of 220kV FRP dry capacitor type wall bushing in Huadian Qingdao Power Generation Co., Ltd to ensure the smooth handover of on-site testing. 

Compared with similar products from domestic and abroad, SF6 frequency conversion series resonant device has the advantages of small magnetic leakage, low loss and noise, meanwhile has high integration, small footprint, convenient move, suitable for using in narrow spaces, and also low storage energy, less damage to the samples.
